Block Polymer

Name:
Block Polymer
Detailed information:
A high polymer whose molecule is made up of alternating sections of one chemical composition separated by sections of a different chemical nature or by a coupling group of low molecular weight. An example is blocks of polyvinyl chloride interspersed with blocks of polyvinyl acetate. Such polymer combinations are made synthetically. They depend on the presence of an active site on the polymer chain that initiates the necessary reactions.See Graft Polymer; Stereoblock Polymer
